Predicting the Arctic Ocean's Future through Its Past and Present



Korea-Arctic Ocean Observing System (K-AOOS)

The Arctic Ocean is a region that has been most susceptible to the effects of global warming, and has been exerting a significant impact on the global climate system. With Arctic warming occurring at a rate faster than the global average, the rapid melting of sea ice is heavily influencing the climate and the adjacent ecological environment, whether it be through heat circulation between the ocean-sea ice-atmosphere, or changes in the oceanographic current, etc.


In order to understand the potential effects of climate change on the marine environment of the Arctic Ocean, there is a need for further research on the physical properties of sea ice motion, biogeochemical systems, and its related mechanisms.


Funded by the Korean Ministry of Oceans and Fisheries, KOPRI has been carrying out a research project titled “Korea Arctic Ocean Observing System,” scheduled over a period of five years from 2016 to 2020.


This project assesses the most rapidly-changing regions in the Arctic Ocean (Bering Sea, Chukchi Sea, East Siberian Sea/ESS), aiming to examine the changes in the atmospheric, physical-biogeochemical marine environment that occur alongside changes in sea ice, while analyzing the causes of the environmental change in the Arctic Ocean to predict future changes.


In August 2016, KOPRI began to conduct a research project named ARAON, which consists of research on the temporal and spatial variation of sea ice distribution in the Arctic Bering Sea, Chukchi Sea, and ESS; unique physical changes of ocean and sea ice; the force of ocean-atmosphere gas exchange; and the physical and biogeochemical processes of marginal sea ice zones.


Through such research, this project aims to achieve a better understanding of the phenomenon of rapid environmental change in the Pacific Western Arctic Ocean, and to construct a map of the Arctic Ocean on a temporal and spatial scale, with the aim to establish the scientific foundation for national strategies addressing global polar issues.
